For those in the region ths is a wonderful day trip. Talalpsee is in canton Glarus...only took us about 30min to get to Filzbach from Pfäffikon SZ.
Park the car at Filzbach and then you take a chairlift up. Like all good swiss mountains there is a restaurant at the top! And there is a decent children's playground. From here there are a few walking trails. The most commong is to walk down to the Talalpsee. It is a paved road (so good for kinderwagons/prams) and not too steep.
Talalpsee is gorgeous. There is a second small restaurant by the shore serving very good (simple) food like a farmer's plate (selection of cold cuts, cheese and bread). There are signed trails, you can walk around the lake (take a dip if the weather is still good), there are some caves to explore. Or for the more energetic a 3hr hike up to the top.
Then to get back down to Filzbach you have three options:
1. chairlift back down (gorgeous views over to the Zurichsee and Walensee, plus the Churfirsten).
2. rodelbahn - like a toboggan ride - down half way and chairlift the remainder
3. trottinet - large scooter - all the way down.
Great easy day trip for those in the area and esp easy to do with children. http://www.wandersite.ch/Tageswander...%20Glarus.html http://ext.sbb.ch/offer/detail/Defau...?id=904&lang=4
